Want a colour coded SharePoint Calendar?

Look no further than CodePlex.

Mark Wilson has built a really useful little add in for SharePoint.

"It has been built so as to be upgradeable from the previous version. If you run the upgrade script as opposed to the deploy script then you will find your old colour calendar lists still work but the option to create a "Colour Calendar List" will be removed. You can obviously just use the new method for any new colour calendars you wish to create.
Thanks for all the feedback so far.
As usual the latest release can be found here"
